Removing data from a session
I am using the following code to remove an attribute from a session
List<User> l=(List<User>) sess.getAttribute("allUserslist");
for(int ii=0;ii<l.size();ii++){
System.out.println("bef"+l.get(ii).getLoginName()+optionSelected[i]);
if(l.get(ii).getLoginName().equals(optionSelected[i])){
System.out.println("in iteration");
sess.removeAttribute(l.get(ii).getLoginName());
List<User> l1=(List<User>) sess.getAttribute("allUserslist");
System.out.println("final size"+l1.size());
}
}
The final size after deletion is still the same as before, where am I going wrong?

Your code removes the attribute listed after the user, but does not remove the user from the list. For this:
List<User> l=(List<User>) sess.getAttribute("allUserslist");
for(int ii=0;ii<l.size();){
System.out.println("bef"+l.get(ii).getLoginName()+optionSelected[i]);
if(l.get(ii).getLoginName().equals(optionSelected[i])){
System.out.println("in iteration");
l.remove(ii)); // Remove user from the list
} else {
++ii;
}
}
List<User> l1=(List<User>) sess.getAttribute("allUserslist");
System.out.println("final size"+l1.size());
